whereby a rim maybe quickly secured npon a Wheel with a minimum ofdifficulty.

A further object Vof 'the inventionis' Tte provide a rim lockemployingplnrality of rim clamps and wherein :all of th-e;- clamps maybe simultaneously shifted to engage the rim securing the `rim inposition.

And the invention has as a still further object to provide a rim lockwhich will be sturdy and secure and which may be readily employed inconnection with conventional motor vehicle wheels and rims.

Other and incidental objects will appear hereinafter.

In the drawing:

Figure 1 is a side elevation showing a conventional motor vehicle wheelequipped with my improved rim lock,

Figure 2 is an enlarged detail sectional view showing the mounting ofthe wedges and clamps employed, and

Figure 3 is a detail plan view, partly in section, this viewparticularly illustrating the locking lever of the device.

Referring now more particularly to the drawing, I have, for convenience,shown my improved rim lock in connection with a conventional motorvehicle wheel 10 having the usual felly 11 and surrounding the felly isa rim 12 removable at the outer side of the wheel or that side of thewheel remote from the vehicle. In carrying the present invention intoeffect, I employ a plurality of bolts or supporting elements 13, which,as shown in Figure 2, are fitted transversely through the felly 11 ofthe wheel from the inner side thereof and threaded upon the bolts attheir inner ends are nuts 14.' The bolts are arranged at suitably spacedpoints circum ferentially of the felly and formed in the outer ends ofsaid bolts 'are slots 15. Slid ably fitting through these slots arewedges 16 having inclined outer side edges and, in this connection, itwill be observed that the outer 'end walls of theslots 15 vvoff thebolts lare ,beveled so that the inclinededges of the ,wedges ywillseatplflat th'ereagainst. The .wedges-.are formed withstraight innerside 4 edgesf'-a'lnd lprojectingjfrom the. wedges l,at

ltheir ends are .stop lugs 17 abutting the .felly.f1i1 spacing thewedges therefrom. Acc'ommodated between the wedges and `the [fellyarerim clamps 19 slotted to" receive the bolts 13 and; ,coactingkat.vcorresponding ends thereof `with-the felly .while the opposite end'sfofsaid-wedges ,are disposedfto engage theirim .12 at :its adj aellt Side.i i l -v Fitting transversely through the *.felyly.,

lambetant.ially mid-'Way between a aan vofthe bolts ;13, -is;a bolt{20;upon ,the outer endgof Y which-eis garranged ,a nut r2.1 fandthreaded .upon svaidfbolttosea-t flat against the outer side'ifaceofithe ffelly lisla plate' .Mounted at the upper edge of this plateis a locking lever 23 pivoted at one end to one end of the plate, thelever being also adapted to seat flat against the felly, and arrangedupon the bolt to normally overlie both the plate and lever is a clamp 26similar to the clamps 19. Extending through the felly at pointssubstantially midway between the bolts 13 as well as at opposite sidesof the bolt 20, are eye bolts 24 and extending through the eyes of saidbolts are cables 25 secured to the ends of the wedges 16 and to thelocking lever 23, these cables connecting all of thel wedges with eachother and with said lever.

As will now be readily understood in view of the preceding description,the lever 23 may, by releasing the nut 21 and disposing the clamp 26horizontally upon the bolt 20, be swung away from the felly 11, as shownin Figure 3, when the wedges 16 will be moved endwise for releasing theclamps 19 so that the clamps may then be retracted and the rim 12removed from the wheel, it being noted in this connection, that the stoplugs 17 of the wedges will coact with the clamps for limiting endwisemovement of the wedges. On the other hand, by swinging the lever 23 inthe opposite direction to seat against the felly, the wedges will beadvanced against the clamps for binding the clamps in engagement withthe rim and locking the rim upon the wheel. This done, the clamp 26 isdisposed vertically to coact with the rim. overlying the plate 22 andlever 23 when the nut 21 is threaded down upon the bolt 20 to bind saidclamp against the rim and lock the lever against movement.

The rim may thus be eltectually secured upon the Wheel with a minimum otditliculty and attention is now directed to the tact that should theWedges 16 become Worn through repeated operation thereof, the nuts 14may be adjusted upon the bolts 13 tor retracting the bolts through thetelly and taking up such Wear.

Having thus described the invention, What is claimed as new is:

1. rThe combination With a Wheel having a telly, and a rim removablysurrounding the telly, ot clamps mounted to engage the rim, Wedgesarranged to coact with the clamps, a bolt extending through the telly, aplate mounted upon said bolt, a lever pivoted upon said plate, meansconnecting all ot the Wedges With said lever whereby the lever may beswung tor shitting the Wedges and binding the clamps in engagement Withthe rim, and a nut threaded upon the bolt tor looking the lever againstretrograde movement.

2. The combination with a Wheel having a telly and a rim removablysurrounding the telly, ot supporting elements projecting trom the tellyand provided With slots, clamps on said elements, Wedges slidable insaid slots to coact With the clamps binding the clamps in engagementWith the rim, and means tor shitting the Wedges.

3. The combination With a Wheel having a telly, and a rim removablysurrounding the telly, spaced supporting means projecting trom thetelly, clamps on said means, and Wedges slidable through said means tocoact With the clamps binding the clan'ips in engagement With the rim.

1. The combination With a Wheel having a telly, and a rim removablysurrounding` the telly, ot bolts extending through the telly, clamps onsaid bolts, Wedges slidable through the bolts to coact with the clampsbinding the clamps in engagement With the rim, and nuts adjustable uponthe bolts tor taking up Wear upon the Wedges.

5. The combination With a Wheel having a telly, and a rim removablysurrounding the telly, ot bolts projecting trom the telly,

clamps loosely mounted on said bolts, and

Wedges slidable through the bolts to coact With the clamps binding theclamps in engagement with the rim.

In testimony Whereot I altix my signature.
